TO-WHOM IT MAY, CONCERN: l

Be it known that I, W'ILLIAM B. yTruasnwnnr.,ot` the city and 'county ofAlbany, and State ot- New York,

have invented a certairi new and useful Improvement in Stoves,particularly adapted to the' construction of cookingfstoves for thevburning of bituminous coal; and I do hereby declare thatA the followingis a full land 'exact description thereof, reference being had totlle'accompanying drawings, makinga part of this specification, thesameletter in each of Athe several figures marking the same part of thestove. In the accompanying drawingsv f l Figurel lis a perspective vviewof my invention, with hearth swung o' from the stove. Figure 2 is avertical section through the centre of the stove from front to back.Figure 3 is a horizontall section of the dre-chamber, taken on theplaneof the red lino T in g. 2.4 v -The nature and object of my improvementare threefold: first, I seek, by the proper application of air to theseveral parts of the iire, or its introduction into the re-chamber, toburn more perfectly bituminous coal in .cooking-stoves, so asto consumethe smoke and gases'which arise therefrom during the ordinaryprocess-.oi`

burning; second, to so construct stoves as to avoid rovertible dues;third, to separate the coal from ,the ashes and refuse matter which havedropped from the dre-chamber with as little trouble and inconvenience aspossible;

all of which I have accomplished in the improvement hereinafterparticularly described. l. 5

The great desideratunl'in the construction of a stove for the perfectcombustion of' the fuel employed is to so apply the air, and in suchquantities, as to supply necessary quantities of oxygen at theparticular points needed for combustion'. The' quantity mustbe suiicientto furnish the necessary amount of oxygen, and at the same time nottoomuch to absorb the 'heat and choke the passage through theescape-lines, thus affecting' unfavorably the draught of the stove.

In my improvement lI have carefully providedv forthe appropriate supplyof air atfthe points of combustion.` l

By anlexamination'oi figs. I and 2, my provisions in these respects willbe seen. l i

In iig. 1, these 'provisions' are seen in the tubes *an a a, as seen inthe back of the 'irmpot through -the opening in 'the top of the stove.These tubes are perforated as represented by the black points or dots,as seen in iig. 1. 'The object ofthese perforations is to allon'j theair which is admitted to these tubes to escape into the fire-pot insmall streams orjets among and upon the solid burning fuel. ;'I'his isto supply that pai-tof theiuel lying against the back'part of tliefire-pot ivlth air, which is admitted to these tubesthrou'gh an openingin the side of thestove seen atv-K in iig. 1. Airis also admitted to thefrontand upper surface oi' theburning fuelin the {ire-pot throughapass'age formed by plates F and v, and bythe grate G, as seen andexhibited at 'm andf, in g. 2, the ceurseoi the air being indicated bythe red arrows atm and j'. The air is supplied to these openings throughdamper-plates seen under the feed-place B in iig. 1, and representedatdainp'er w in g. 2. Air is applied to the Jrire-chamber at the backpart oithc fire-chamber, and at' the upper partrot the fuel, throughopeningsI between the plates seen in iig. 1, at n, and represented iniig. 2 by the red arrow enter 'irig theiirc-potat The air is suppliedto4 these openings by means of 'a chamber connecting with. the same,

having its outward orifice atj, as seen at iig. 1, as well also as bymeans oi' air from the tubes in the'baek of Athe` repot, as seen infig.. 2, and represented by tube a. Air is also supplied at -the Vbottomof the repot through tho grate Gr, as seen in 2.' In this mannerevery'part of the f uel 'in the tire-pot is supplied with the requisiteamount of oxygen to facilitate the combustion thereof.

I construct ary-stove, to accomplish my second purpose, that is, toavoid revertible fines,` as follows:I This is particularly'exhibited 'iniig. 2, 4:representing a verticalfsectionoi the stove, in'whicli areseen thefeed-plaee BA, the tire-'chamber A,'the escape of theproducts'of combustion, as indicated by the black arrows, from the topof the re-chambcr into the space O formed by -the top of the oven D-andthe top' plate and the covers of the "stove, connecting wtlrtheescape-due at O, forming a heating-current over the top of the oven. Theproducts of combustion also' pass outbetween' the tubes forming the backof the dire-pot, entering 'the space E; between 'theire-pot and theoven-1.), and passing thence underneath and up the back of the oven,connecting with the SmQeSape-ilue at O, thus forming a heating-currentunderneath andaround the sides of 'the oven. In this way my fins aredirectkand yet they encircle the oven, heating equally every partthereof.

The third branch of my improvement consists in separating the coal fromthe refuse matters which have dropped from the fire-chamber upon undinto the separator. This rseparator or sifter isseen' in figs.. 1 and2,V and is represented by letter L. This siftec is situated benenthlthcgrate'G to receive the coals, ashes, und other refuse I'nattcr which mayfall or be dumpedrupon it. By means of a. hook acting upon the' shaft Z,the sifter may be vibruted to separate the ashes from th'e cool. VAfterthissiftinghas takenplace, the sifter is dumped into the box M, by meansof o lever acting upon the shnft Z; the fishes are collected in the box4N.

Thus the coals axc sepm'stcd from the ashes without any inconvenience,and with little labor.

In the drawing, iig. 1, H is the hearth of the stove, lmode separatefrom the stove, und attached to it by means of n hinge, so that it maybeclosed and opened at pleasure. ,The box `for the coal separated fromth'e ushers is placed. in the hearthH, as seen in iig. 1, ondrepresentcdin fig. 2, at M. p p

Having thus fully described my imprQ ve111ent,-[ will proceed todescribe what I cicim ns my invention, and desire to secure by LettersPatent. l 1. I claim grate Gr, combined with plates 'F und v,constructed substantially in the manner and for the purpose abovedescribed. p V

' 2. I claim grate Gr, plates F and v, in combination with plates d ande, for introducing cir et m end'n, constructed substantially in thomanner and for vthe purposes above described.

3. I claim the irefchnmber, constructed as nabovc, in combina-tion'wththe sfter L, snbstantially in the manner and for theV purposes abovedescribed. I

4..I claiml the sifter L, in combination with the boxes M und N and thegrote-G, substantially in the manner and for the purpose abovedescribed. J V

5. I claim the hearth H, constructed substantially in the manner und forthe purpose herein described.
